This penultimate episode of the series explores the challenges and opportunities for monitoring and enforcement efforts. Policing our vast oceans is already presenting many difficulties, and with illegal, unreported and unregulated (IUU) fishing operators set to adopt new behaviours in a warming world, how can enforcement efforts adapt to tackle the threat?

In part two, Grace and Lauren are joined by Peter Horn, Aaron Delano-Johnson and Tom Hlavac to take a deeper look at how illicit fishing laws are enforced across the vast expanse of the world's oceans.
